Hi Chris,
(1) Majority of our maintenances -- like this one tonight, which happens about once a month, are zero-downtime maintenances. An existing session may get an automatic reconnect, but it should be transparent to the end user. Our goal with the Health page is to over communicate, but you bring up a good point here as the announcement seems more ominous than what I've described. I'll take the action to discuss with our operations team so we are clearer on the expected experience in the future.
Every now and then, we'll need to perform a maintenance that results in downtime. And when that happens, we will explicitly state this on the health page, and aim to perform these during low traffic hours.
(2) The current offering today from Adobe is a multi-tenant service, and unfortunately, it's impossible to find a time that works perfectly for all our customers. Ultimately, zero-downtime for all maintenances is our goal. If you need something that is more catered to your needs, the good news is that we have a partner today who can offer LCCS on a single-tenant basis with customized SLAs.
